Spinal cord Segmentation

The video tutorial explains the segmental organization of the spinal cord and vertebral column, highlighting the discrepancies between vertebral and spinal cord segments. It covers the number of segments in cervical, thoracic, lumbar, and sacral regions, and explains why there are 7 cervical vertebrae but 8 cervical spinal cord levels. The tutorial delves into embryological reasons for these discrepancies and illustrates how spinal nerves exit in relation to vertebrae. It concludes with a discussion on vertebral segmental discrepancies across different spinal regions.

How do spinal cord levels and vertebral levels relate in the cervical region?

What happens to the relationship between spinal cord and vertebral levels as you move down to the thoracic region?

In the lumbar region, how do spinal cord levels compare to their associated vertebral levels?
